I bought one of these at Goodwood and fitted it when I got home in the eve. Took about an hour to do & the instructions were spot on.
As others have mentioned, the noise is awesome around 3k and upwards on revs. Powerwise, it seems a little perky, but I wouldn't say a huge difference, but then you aren't paying a lot for an extra 4-5bhp.
As to fuel economy, my first few tanks came out about the same as before, then they dipped lower, (because I was enjoying the new soundtrack!), the next few tanks were driving sensibly, (boring I know), and fuel economy picked up, slightly improved.
